Specification of Letters Patent.

Patented Sept. 2, 1919.

Application filed November 16, 1917. Serial No. 202,284.

To all whom it may concern:

lie it known that I, EDWARD THOMAS, a citizen of the United States, residing in New York city, in the county of New York and State of New York, have invented certain new and Useful Improvements in Typel Vriting Machines, of which the following is a specification.

This invention relates to an improvement in ty iiewriting machines, and more particularly to a collating device for assisting in assoiu'rblin work-sheets on the platen.

Above t 1e platen on the carriage or platen frame there is mounted a collating board or table on which the several work-sheets may be assembled in various relative positions. This collating-board is supported so that it can be shifted from a collating position to a delivering position such that the assembled work-sheets thereon can be transferred to the platen. The collating-board is pivotally mounted for this purpose, so that after the sheets have been assembled the lower ends thereof can be swung and then slid down in front of the platen between the paper-apron, the front rolls and the platen, thereby permitting the worksheets on the collating-board to be backwardly inserted in a pack around the platen, to be gripped by the platen and feed rolls before withdrawal from the impaling pins.

Other features and advantages will here inafter appear.

In the accompanying drawings,

Figure 1 is a vertical section taken from front to rear, showing the collating-board in its raised position, in which position the work-sheets are asseu'i'bled thereon.

Fig. 2 is a View similar to Fig. 1, except that the collating-board has been swung down to deliver the assembled sheets to the platen.

Fig. 3 is a spread erspective view, show ing details of an ad ustable connection between the collating-board and its support ing brackets.

Fig. 4 is a detail section through the collating-board on the line 4.4 of Fig. 5, showing the mounting of the impaling studs and supporting frame therefor.

Fig. 5 is a perspective view, showing the collating-board in its assembling position.

The platen 1 is mounted to rotate on a platen frame 2, which is mounted, in turn, on the usual typewriter carriage. The platen 1 is rotated either by hand-knobs 3 or linespace mechanism, indicated in general at 4. To assist the platen in feeding work-sheets and for maintaining work-sheets smooth on the platen, there are provided pressure feed rolls 5, which are normally held in engagement with the platen 1. These pressure feed rolls 5 are in sections and in pairs, so as to engage the platen at several points along the length thereof and at two lilies at different points in a circumferential direction. The pressure feed rolls 5 are mounted on shafts 6, which, in turn, are supported by I'I'OSSBd bell-cranks 7 and 8. The bell-cranks 7 and 8 are pivotally mounted at 9 and are provided with arms 10 and 11, which normally engage the indented sides 12 of a rock shaft 13. When the rock shaft 13 is rotated to force the arms 10 and 11 out on the circumference of the rock shaft, the rolls 5 are moved out of engagement with the platen 1 and the work-sheet carried thereby. This either releases the work-sheets, so that they can be easily removed from the platen or permits the insertion of fresh work-sheets on the platen. This is the usual Underwood pressure feed roll mechanism, and the shaft 13 is operated from a release key 1a, which is connected to rock the shaft 13 by'means of a link 15 and an arm 16 provided on the rock shaft 13.

In an ordinary typewriting operation, the work-sheets are fed to the platen 1 at the rear of the same, and are gulded to the bite of the platen by a work-table or plate 17. The work-sheets coming from the plate 17, according to the present invention, are directed around the platen 1 with the assistance of the pressure feed rolls 5, by means of a paper-apron 18, which may comprise sections 18 joined to each other at 18". The pressure feed rolls 5 extend through openings between said sections and bear against the platen 1 or the work-sheets carried by the platen. The paper-apron 18 is connected to move with the pressure feed rolls 5 toward and from the platen 1, by having one of the shafts 6 extend through loops or bends 19 provided in the paper-apron 18. Since the paper-apron 18 is pivotally connected at 20 to the plate 17, it may thus move toward and from the platen 1 with the movement of the pressure feed rolls 5. In the meantime, the platen may have been raised by means of the case-shift key (not shown), thus freein the platen from the usual wing-scales. he work-sheets can thus be inserted easily on the platen 1. Also, because of the fact that the end sections of the apron 18 extend up a COl'lSldGY- able distance at the front of the platen the work-shvets ma be inserted at the .rdnt almost as readily as at the back of the platen when the apron is moved away from the platen.

For the purpose of assembling a plurality of work-sheets with interleaved carbon sheets in various relative positions before inserting them on the platen 1, there is provided a collating boar or table 21 mounted on the platen frame 2, so as to travel with the laten. There are provided on the sides of tie platen frame 2 supporting brackets 22. These supporting brackets 22 preferably have slots 23 to afford adjustability for height between the brackets 22 and brackets 24 )rovided on the collating-table 21. The ta 1e 21 may pivot relatively to the brackets 22, so as to swing from the collating position of Fig. 1 to the delivering position of Fig. 2. The adjustable connection may also permit the locking of the table at different levels to locate the table at difl'erent distances from the platen 1.

Mounted in each slot 23, there is a slide 25, which has its greatest length in the direction of the length of the slot 23, soar: to prevent its turning in the slot. The slide 25 is provided with a hub 26, which forms a mounting for an arm 27 rigidly secured to the slide, and a journal for one of the brackets 24, through an opening 28 in which the hub 26 extends. The slide 25 is provided with a screw 29 formed thereon, which is engaged by a set-screw or nut 30. The nut 30 can be tightened to hold the slide 25 in any adjusted position along the slot 23, so as to selectively determine the height at which the table 21 is located. On the opposite side from the screw 29 of each bracket 22, one of the brackets 24 is pivotally mounted on the hub 26 and maintained thereon by means of a nut 31, which threads onto a screw-bolt 32" formed on the slide 25 beyond the hub 26. There-is provided one of these combined connections having fixed position-determining adjustments and Working movements on each side of the table 21.

There is also rovided one of the arms 27 at each side 0 the table 21.- These arms support a rod 38, which forms part of a locking means holding the table 21 in a collating position. Tl'llslofik'lililg means'includes a air of latches 34, w h are provided with sockets 85 engaging ins 37 provided on the table-brackets 24. 0th of the latches 34 are secured to the rod 33 to rotate with the same, and the latches are held in their active position by .one or two springs 39, each of which on ages a latch 34 at one end and an arm 2 at the other end. The limit of movement of the latches is determined by a stop-pin 36. One oi the latches 34 may be provided with a fingerpieee 40, whereby both of the latches may be released sinmltaneously. The latches 31 move up and down with the table 21 when its elevation is semi-pcrumn mtly changed, and act also as brackets when the table 21 is in a collating position, preventing unsteady movement.

For the purpose of holding the worksheets as they are assembled on the collating-board 21 and until they are delivered to the platen 1, there are provided iu'ipaling studs 41, which may engage perforations 42 in the work-sheets 43. The studs are arranged in one or more series on a sliding frame 44 mounted on the table 21. This frame 44 may be retained upon the table 21, by having the shanks of the impaliug studs 41 extend into slots 45 provided in the table 21 and running lengthwise of the work-sheets 43. These studs 41 may be headed at 46, so as to engage the under side of the table 21, to prevent the studs 41 from passing through the slots 45 and thus hold the sliding frame 44 to the table 21.

One or more handles or knobs 47 may be provided on the sliding frame 44 to permit it to be easily moved along the swiveled table 21. The frame 44 is held in its normal position by a s ring deteut 48, Fig. 1, which engages a note provided on the under side of the slide 44, the table 21 being provided with an opening to permit access of the detent 48 to the slide 44. After a delivery, the table 21 is returned to its normal position corresponding to Fig. 1, preferably by hand, but a sprin may be used, against the tension of which the table may be rocked to the Fig. 2 position. The limit of the downward swing of the table 21 is determined bv one or more stops 50. Indicators 51 are provided. to show the upper limit beyond which the bottom edges of the worksheetsmus't not go in collating, in order to havethe Work-sheets gripped by the platen and rolls 5 when do ivered thereto while still on the frame 44.

In operation, the table 21 is adjusted to the height desired, either to accommodate Work-sheets of certain length or to suit the convenience of the operative, and locked at this height by tightening the nut 30. The latches 34 move with the slides 25 and thus with the table 21 for different elevations of the latter and act as brackets as Well as locking means. As the arms 27 are secured to the slides 25 they act on the opposite sides of the brackets 22 to the nuts 30, so that the pivotal movement of the brackets 24 relative to the hubs 26, and thus relative to the slides 25, is not impeded. The collating-table 21 is held in the normal inclined position of Fig. 1 by means of the latches 34-, and the impaling sliding frame 44 is held in the upper position, also shown in Fig. 1, by means of the detent 48. The work-sheets may be assembled one by one with the interleaved carbon sheets and held in their assembled position by impaling them on certain of the impaling studs 41. The impaling studs 41 used must be the ones which will bring the bottom edges of the work-sheets at least down to the indicators 51; otherwise the Work-sheets when delivered to the platen will not reach the bite between the front roller 5 and the platen 1.

When all of the work-sheets have been collated upon the table 21 in the Various relative positions necessary to bring certain desired lines on the several sheets into register with one another, then the table 21 may be swung down to the Fig. 2 position after releasing the latches 34. In this position it will be ready to deliver the worksheets to the platen 1. The pressure rolls 5 and the paper-apron 18 are moved away from the platen 1 either before or after this is done, to enable the work-sheets to be inserted on the platen at the front thereof.

The slide 11 having thereon the impaling studs 41, and thus carrying the worksheets, ean he slid down from the Fig. 1 position to the Fig. 2 position, so that the bottom edges of the Work-sheets will enter the opening 49, between the paper-apron 18, the rolls 5 and the platen 1. By inserting the finger in a groove 49, the worksheets, when they are short, may then be stripped from the impaling studs 41; and the feed rolls 5, together with the paperapron 18, may be brought u against the platen 1, so that the work-s eets will be gripped to the platen. The platen may then be reversely rotated to bring the initial line of writing, which is superposed on the several sheets, to the printing point.

After inserting the work-sheets, around the platen, the collating-table is raised to ihe position corresponding to that of Fig. 1, in which position it is caught and locked by the latches 34. The slide 44 can be returned to its normal upper position, ready for the collating of a new set of worksheets.
